PROBLEM TO BE SOLVED: To provide a thrust roller bearing for effectively preventing nipping of a cage, in the thrust roller bearing of integrating three parts. SOLUTION: This thrust roller bearing 11 has first and second bearing rings 14 and 15, a plurality of rollers 12, and the cage 13. The first bearing ring 14 has a first bearing ring 14b, a first step part 14e on the outside in the radial direction more than the first beating ring and a cylindrical outer peripheral collar part 14c formed by bending an outer edge of the first step part 14e. The second bearing ring 15 has: a second bearing ring 15b; a second step part 15e on the inside in the radial direction more than the second bearing ring 15b; and a cylindrical inner peripheral collar part 15c formed by bending an inner edge part of the second step part 15e. Predetermined clearances are always formed between an outer peripheral surface of the cage 13 and the outer peripheral collar part 14c, and between an inner peripheral surface of the cage 13 and the inner peripheral collar part 15c.
